Digital common lines for X7 and X8 are not common to each other.
The DCOMx line should be connected to the 0V of the I/O supply when using sensors of type
"Source" with digital inputs.
The DCOMx line should be connected to the 24V of the I/O supply when using sensors of
type "Sink" with digital inputs.
